Trapezius muscle EMG as predictor of mental stress

Published: 05 October 2010 Publication History

Abstract

Stress is a growing problem in society and can, amongst others, induce musculoskeletal complaints, related to sustained muscle tension. The ability to measure stress with a wireless system would be useful in the prevention of stress-related health problems. The aim of this experiment was to derive stress levels of subjects from electromyography (EMG) signals of the upper trapezius muscle. Two new stress tests were designed for this study, which aimed at creating circumstances that are similar to work stress.
An experiment is described in which EMG signals of the upper trapezius muscle were measured during three different stressful situations. Stress tests included a calculation task (the Norinder test), a logical puzzle task and a memory task, of which the last two were newly designed.
The results show significantly higher amplitudes of the EMG signals during stress compared to rest and fewer gaps (periods of relaxation) during stress. Also, mean and median frequencies were significantly lower during stress than during rest. The differences in EMG features between rest and stress conditions indicate that EMG is a useful parameter to detect stress. These results show opportunities for the inclusion of EMG sensors in a wireless system for ambulatory monitoring of stress levels.

In today's world, which is filled with stressful situations, researchers are diligently studying the manifestations of stress. They hope to, among other things, come up with practical solutions for monitoring stress levels. As stress (whatever the definition) affects muscles, electromyography (EMG) frequencies are observed in the context of stressful situations and juxtaposed with an individual's self-report. This juxtaposition helps researchers determine if tests designed to, say, mimic the stress in the workplace define a notable relation between the EMG signals and the subjects' reports. This remarkable paper by Wijsman et al. is full of graphical elements that support their study of EMG signals of the back/neck trapezoid muscle as a potential predictor for mental stress. Researchers examined data from 30 subjects who were put through three stressful situations (calculations, logic puzzles, and memory tests). Of those, 22 individual datasets were used for a remarkable statistical analysis. The goal of the study was to propose and validate a protocol of stress induction, confirm that stress can be detected from the EMG, and investigate the manifestation of stress in the EMG spectrum. What we learn from this paper is that the designed protocol meets these goals and indicates an EMG shift toward lower frequencies during stress, a situation not unlike what happens to muscles under fatigue. So, what is next__?__ Apart from looking into the origins of differences detected in stressful scenarios, perhaps a wireless commercial product can be built to monitor stress in an ambulatory setting.
